Recommended Method
Based on representative well log data for Maple City, the most common subsurface sequence consists of thin surficial gravel or topsoil, followed by alternating layers of sand, gravel, sand-with-gravel, and clay spanning the upper 200 ft. Sand and gravel units, often containing interbeds of clay, are the dominant aquifers and usually yield high enough flow (5-15+ GPM) for typical residential supply. The static water level is intermediate to deep, reflecting locally varied perched and unconfined aquifer conditions. Drilling is primarily by rotary with PVC or steel casing, and cement or bentonite grouting is commonly applied to ~50-100 ft. Intervals with significant clay serve as partial aquitards but sand and gravel units are persistent and productive across the area. Most residential wells are completed between 60-120 ft, while high-capacity or deep wells may go to 180-200 ft or more.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 3 ft | Topsoil/Gravel | Thin surficial deposit, commonly topsoil or fine gravel. | Color: Brown/Gray Hardness: Loose |
3 – 20 ft | Sand (with some gravel and/or clay) | Medium to coarse sand, occasionally with minor gravel or clay layers. | Color: Tan/Yellow Hardness: Loose-Moderate |
20 – 45 ft | Sand & Gravel (with occasional clay layers) | Predominantly sand and gravel, few thin clay or silty interbeds. | Color: Tan/Gray Hardness: Loose-Moderate |
45 – 70 ft | Clay/Silty Clay (with sand or gravel) | Stiff clay or silty clay, minor sand or gravel seams. | Color: Gray/Red-Brown Hardness: Stiff |
70 – 120 ft | Sand & Gravel | Major water-bearing sand and gravel aquifer, good yield for residential wells. | Color: Tan/Gray Hardness: Loose |
120 – 200 ft | Mixed Sand, Gravel, and Clay (grading finer or coarser in places) | Repeating beds of gravel, clay, sand, and sand/gravel mixtures; thickness of units variable, water-bearing zones present throughout. | Color: Multicolored (gray, tan, red-brown) Hardness: Variable |
